Having committed their crimes, these individuals are now serving their sentences and sharing their stories from within prison walls, shedding light on some of the nation’s most notorious murders.

Returning this Sunday, November 9, Oxygen’s Snapped: Behind Bars unveils a brand-new season filled with chilling confessions and startling revelations from inmates across the United States.

“I just made a lot of bad decisions,” confessed one female inmate in the trailer for the series’ third season, which airs on Sundays at 6:00 PM ET/PT, released on October 14.

This upcoming season will take audiences inside prison facilities to reexamine some of Snapped’s most unforgettable cases, offering fresh perspectives from those who were convicted.

According to a press release from the network, “These exclusive jailhouse interviews offer a narrative from the accused’s viewpoint, integrating archival footage from previous Snapped episodes to elaborate on the case details. The episodes also feature new insights from experts who delve into the psychology of the offenders.”

Snapped: Behind Bars, produced by Jupiter Entertainment, will also feature friends and family who haven’t spoken out before who are now willing to “sit down and share emotional statements and current updates” about how the crimes impacted their lives.

As a narrator teased in the promo, the all-new season will feature “first-hand accounts from the inmates at the center of the most horrific crimes” that have left “families destroyed and lives ruined.”

Those behind bars at prisons across the country admitted to “still being in denial” about their new life locked up, but agreed to share grisly details of their crimes as the cameras rolled.

“She was screaming,” one inmate remembered, “telling me to stop and I couldn’t.” 

Others reflected on what led them down the path of self-destruction. 

“I did her wrong. I led myself wrong,” one man confessed, as another admitted, “I think I was under her spell and she knew that.”

Yet another female inmate promised that she was “here to tell the truth.”

But not everyone seemed to have accepted their fate in lockup. 

“I’m sitting in prison,” another female inmate alleged, “because law enforcement could’t find anyone else.”

The series will draw its cases from Snapped, which just wrapped its milestone 35th season in October.
